The Colts have signed linebacker Jon Bostic, according to a team announcement. Bostic will look to get back on track after spending the entire 2016 season IR all last season. 
Indianapolis ranked 32nd in DVOA against the run in 2016, and placed 31st in DVOA against opposing tight ends, so the team has been prioritizing help in the front seven. Bostic becomes the fourth free agent linebacker to join the Colts this season, following John Simon, Sean Spence, and Barkevious Mingo.
Bostic, a former second-round pick, began his career with the Bears and played in all 16 games with nine starts in his frosh campaign. He finished up that season with 57 tackles, two sacks, and an interception. In 2014, he set a new career watermark with 83 tackles. A trade shipped him to the Patriots before the 2015 season, but he wasn’t as productive. He was again traded to Detroit in 2016, but it turned out to be a lost season.
